How it works
The City's Building Services page says you need a permit to construct, repair or alter a building or structure. It lists no size or height cutoff below which a shed or deck needs no permit, and no exemption for garages or carports. The City has an application package for renovations, additions and accessory buildings. Confirm with Building Services before you start.
Zoning also limits accessory buildings. In R, RR and RM zones, accessory buildings total at most 90 m², 5.5 m high and one storey, and must sit at least 1.0 m from a rear or side lot line. A garage or carport off a lane must be at least 1.5 m from the lane. In A, R, RR and RM zones, they may take no more than two-thirds of the rear yard width or 50% of the lot area behind the house. In the A zone the height limit is 4.5 m. See Zoning Bylaw 5105 section 6.10.
